Cerebro (Spanish for "Brain") is a device that the X-Men (in particular, their leader, Charles Xavier) use to detect mutants.


Original Timeline

X-Men: First Class

An early version of Cerebro exists in an unnamed CIA science facility, built by the young Hank McCoy to amplify brainwaves. It it used by Xavier to find and recruit mutants for training in order to oppose Sebastian Shaw. It is later destroyed by Riptide as Shaw searches the facility for the young mutants.

Emma Frost comments on her perception of Xavier's increased telepathic range when using Cerebro, which she feels despite being some thousands of miles away.

X-Men: Days of Future Past

To be added


Cerebro is a massive device that fills a spherical room in the basement of Xavier's School. The helmet interface is similar to the version seen in the comics, although the bulk of Cerebro's machinery is contained in the surrounding walls. While in use, three-dimensional images of the minds scanned by the device appear around the user. Unlike the comics' version of Cerebro, the film version can detect both human and mutant minds with ease. The unique signature of mutant brainwaves is shown in the first film by the mental images of humans depicted in black and white, while those of mutants show up in color. In the first film, Professor X mentions to Wolverine that Magneto helped him build it, and therefore knows how to construct helmets with circuitry to block its detection abilities. Cerebro is sabotaged by Mystique so that it injures Professor X, putting him into a coma. The only person seen using Cerebro effectively in the films is Xavier; Jean Grey successfully used the device to locate Magneto in the original film, but the input overwhelmed her nascent telepathic power and left her stunned. This has not been mentioned in the comics, although the Magneto of the comics can use Cerebro, and has designed similar devices.

X2: X-Men United

The device was copied and modified by William Stryker in his plot to have a brainwashed Xavier use his Cerebro-amplified powers to kill the world's mutants, and was later further modified by Magneto to kill humans. Stryker forced Magneto to reveal information regarding Cerebro, as Magneto reminded Storm that he helped Xavier build the device. According to the film, it is difficult to pinpoint the location of mutants who have the ability to teleport and are constantly in transit, such as Nightcrawler. Mutants appear in red, and humans in white.

X-Men: Days of Future Past

In 1973 Hank and Charles had built a version of Cerebro in the subasmemt of the X-Mansion.

New Timeline

X-Men: Days of Future Past

Charles uses cerebro to locate Mystique. After it malfunctions, Charles breaks down due to him having not used it for so long. After some encouragement from Logan and his future self Charles tries again and is able to find her. While he is unable to talk Raven out of killing Trask he is able to find out she is going to Washington D.C to kill him.

X-Men: Apocalypse

During the reawkening of Apocalypse an earthquake cured which was felt halfway around the world. Deciding to investigate Hank and Charles use Cerebro and find Moira MacTaggert at the site. Later when Raven came to the X-Mansion to enlist the assistance of Charles to help her find Erik after the death of his family. He,Raven, Alex, and Moira go to Cerebro to locate Erik. When Charles makes contact he tries to convince Erik to come back with to the, to help him. However the conversation is interrupted by Apocalyspe who manages to take over Xavier and Cerebro and uses the latters enhancing of his powers to cause various men of the worlds military to fire all of their rockets into space and disarming all of the worlds military. Charles in a desperate attempt to prevent Apocalyspe orders Alex to destroy all of Cerebro. Using his powers Alex proceeds to destroy Cerebro and the room itself in the process. Later after the defeat of Apocalyspe Jean and Erik rebuild the X-Mansion and with that Cerebro as well.

Mutants found in Cerebro


  • Cerebro is not seen in X-Men: The Last Stand.
  • In both films, Magneto's helmet is capable of blocking the telepathic signals from Cerebro, as well as any telepathic mutants.
  • In X2: X-Men United, Xavier states Magneto helped him build Cerebro; yet in X-Men: First Class, it is Beast who is shown to create it. It is possible that between X-Men: First Class and the first film, Xavier and Magneto set aside their differences and built the one in the mansion off of Hank's design.
